In order to build a safer tomorrow, both for the planet and for people, industries are creating new technologies and solutions. While change can take time, examples of positive trends can be seen in each sector. The rise of heat and exhaust recovery, for example, has been made possible and increasingly efficient by new product innovations.

Omnia Limited's chemical complex in Sasolburg, South Africa, relies on imported ammonia for nitric acid and ammonium nitrate production. In Richards Bay, the choice of Vahterus Plate & Shell Heat Exchangers (PSHEs) by ThyssenKrupp Industrial Solutions South Africa and Zonke Engineering has significantly optimized cost and performance in ammonia recovery systems.

Vahterus Plate & Shell Heat exchangers play a pivotal role in thyssenkrupp Industrial Solutions' urea plants, optimizing the hydrolysis and desorption phases. Since 2012, Vahterus has been a key supplier, delivering compact, cost-effective solutions that meet stringent safety standards. These heat exchangers, used between the desorber and hydrolyser, have proven their longevity and reliability, with the oldest unit surpassing 15 years of continuous service.

In the pursuit of efficient and compact solutions for Gas-to-Liquid, Power-to-Liquid, and Power-to-Gas processes, INERATEC has found a reliable ally in Vahterus Heat Exchangers. Successfully integrated into INERATEC’s container-sized chemical plants, Vahterus PSHEs play a pivotal role in ensuring high thermal efficiency through effective heat recovery and compact heating and cooling, particularly exemplified in the Power-to-Liquid process at their Karlsruhe site, marking a successful collaboration between the two innovators.

While standards have helped the refrigeration industry to improve and set safety requirements, the International Institute of Refrigeration is proposing a working group to enhance refrigeration safety.

As Plate & Shell Heat Exchangers gain acceptance in the process industry, many potential users are seeking validated performance data of the latest commercial plate technology so that they can be assured of adequate operation. HTRI, a leading source of process heat-transfer technology, is working with Vahterus to assess the PSHE performance for liquid-liquid and boiling service.

Pölkky replaced an old tube heat exchanger in Taivalkoski production unit with a fully welded 12-MW Vahterus Plate & Shell heat exchanger. The compact size makes it easier to install in a production plant.

Impala Platinum, the second-largest platinum producer globally, faced a critical cooling challenge in their South African mineshafts, where outdated technology and maintenance issues posed risks. This article discusses how they successfully upgraded their cooling system by adopting innovative Plate & Shell heat exchangers, marking a significant shift in technology for large-scale cooling applications.
